Substitute Part Grouping Explanation

Substitute parts for the MTSW-132-07-G-D-240 are qualified based on the following critical parameters that define functional interchangeability:

Connector positioning and pitch: 64 positions, 2 rows, 0.100" (2.54mm) mating pitch and row spacing
Contact type and termination: Male pin contacts with solder termination
Mounting and fastening: Through-hole mounting with push-pull fastening
Electrical performance: Current rating of 3A or higher, operating temperature range encompassing -55°C to 125°C
Compliance and material standards: UL94 V-0 flammability rating, RoHS compliance, gold-plated mating contacts

The four substitute parts listed below meet these core criteria while permitting variations in contact material, insulation material, contact length, and contact finish thickness—parameters that do not affect the fundamental connector function within the specified electrical and mechanical envelope.

Engineering Selection Recommendations

All four substitute parts maintain Active product status and full RoHS compliance, ensuring long-term availability and regulatory alignment with the original MTSW-132-07-G-D-240.

3-826632-2 (TE Connectivity AMPMODU Mod II): Offers the highest current rating at 5A and extended upper operating temperature to 105°C. The TE Connectivity part features brass contacts and PBT insulation. Insulation height is 0.110" (2.79mm), which is 0.010" higher than the original. This part is suitable for applications requiring higher current capacity within a narrower temperature range.

77313-124-64LF and 77313-824-64LF (Amphenol ICC BERGSTIK®): Both Amphenol parts provide the widest operating temperature range at -65°C to 130°C, exceeding the original specification at the upper limit. These parts are functionally identical except for contact finish thickness on the mating surface (30.0µin versus 15.0µin). Both feature phosphor bronze contacts matching the original material and maintain 0.100" (2.54mm) insulation height. REACH status is Affected for these parts, whereas the original is REACH Unaffected.

A1-64PA-2.54DSA(71) (Hirose A1 Series): Provides the most compact overall contact length at 0.454" (11.54mm) and operates within a narrower temperature range of -55°C to 85°C. The Hirose part includes a 200V voltage rating specification not provided for other parts. Brass contacts and PBT insulation are used. Packaging is supplied in Tray format rather than Bulk.

Selection among these substitutes depends on application-specific requirements for current capacity, operating temperature range, physical envelope constraints, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the 3-826632-2 be used as a direct replacement for the MTSW-132-07-G-D-240?

A: The 3-826632-2 is mechanically and electrically compatible for 64-position, 2.54mm pitch applications. However, the insulation height is 0.110" (2.54mm) compared to 0.100" on the original, and the operating temperature upper limit is 105°C versus 125°C. Verify that your application does not require the higher temperature capability or the exact insulation height of the original part.

Q: What is the difference between the two Amphenol BERGSTIK® parts (77313-124-64LF and 77313-824-64LF)?

A: Both parts are identical in all critical parameters. The only difference is the contact finish thickness on the mating surface: 77313-124-64LF has 30.0µin (0.76µm) while 77313-824-64LF has 15.0µin (0.38µm). Both meet the gold plating specification and provide equivalent electrical performance.

Q: Does the Hirose A1-64PA-2.54DSA(71) have any physical compatibility issues?

A: The Hirose part has a shorter overall contact length of 0.454" (11.54mm) compared to 0.430" on the original MTSW-132-07-G-D-240. Additionally, the operating temperature range is limited to -55°C to 85°C, which is narrower than the original -55°C to 125°C specification. Confirm that your application does not require operation above 85°C.

Q: Are all substitute parts RoHS compliant?

A: Yes, all four substitute parts are RoHS compliant. The original MTSW-132-07-G-D-240 is RoHS3 compliant, while the substitutes are RoHS compliant. Both certifications meet current regulatory requirements.

Q: What is the difference in packaging between these parts?

A: The MTSW-132-07-G-D-240, 3-826632-2, 77313-124-64LF, and 77313-824-64LF are supplied in Bulk packaging. The Hirose A1-64PA-2.54DSA(71) is supplied in Tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Can I use the TE Connectivity 3-826632-2 in applications requiring the full -55°C to 125°C temperature range?

A: No. The 3-826632-2 operates only to 105°C maximum. For applications requiring operation up to 125°C, use the Amphenol BERGSTIK® parts (77313-124-64LF or 77313-824-64LF), which are rated to 130°C.

Q: What is the current rating difference between the original and substitute parts?

A: The MTSW-132-07-G-D-240 is rated at 3A. The TE Connectivity 3-826632-2 is rated at 5A, providing higher current capacity. The Amphenol and Hirose parts are rated at 3A per contact, matching the original specification.
